Reservations are available at this 27-site Forest Service campground along the Warm River, though a mix of first-come, first-served spots gives late-arriving campers a reasonable shot at entry, particularly in the northern loop. Sites run $25 per night and accommodate RVs up to 45 feet with electric and water hookups. No pets are permitted. The campground sits along the Mesa Falls Scenic Byway, putting it within easy reach of campsites near Ashton and well-positioned for day trips to Mesa Falls and the Bechler corner of Yellowstone National Park.
The Warm River runs directly through the property, and water access is the defining feature here. Despite the name, the river runs cold, and tubing, wading, and fishing draw consistent activity from families throughout the summer. Sites in the northern half of the campground, across a small bridge, tend to offer more separation from neighbors. Several sites in the southern loop sit close together with little buffer between them, and crowding has been a recurring complaint from reviewers. Road noise from the byway is audible during the day, though Annie C. notes that "the river covers the road noise" once traffic thins after dark.
Vault toilets are on-site and reviewed as consistently clean. No showers or sinks are available. Firewood is sold by the camp host, who reviewers describe as attentive and friendly. A railroad grade trail accessible from the campground is suitable for mountain biking. Mosquitoes can be heavy, especially early in the season, so insect repellent is worth packing. Book well ahead for summer weekends, and prioritize upper-loop sites for more space.
